Is it possible to make a 2nd order CR LPF or HPF where the cut off frequencies for each pole are equal?
Here is a calculator for this system which includes the transfer function.http://sim.okawa-denshi.jp/en/CRCRkeisan.htm
I figured that I need to try to solve the denominator of the transfer function in this way and impose the restriction that both roots of S must be equal, but I'm not sure how to do that.
